NUT-LOGK.

Specifica.tion of Letters Patent.

Patented Aug. 8 1905.

Be ie known ehat I, FRANK C. ANDERSON a cieizen 0f ehe United Stabes,residing et Cincinnati, in ehe couney of Hamilton and Staee 0f Ohio,have inveneed eertain new and useful Improvements in Nut-Loeks, 01 Whi0hehe following is a full, clear and exact descrip tion, reference beinghad eo ehe aeeompan'ying dreewings, forming part of ehis speoification.

My inveneion relaees eo im rovements in nueloeks designed pareicular yf0r railway frogs and crossings, ehough equally eapable of use 0n fishplates f0r unieing ehe meeting ends 0f rails 01 in any oeher situaei0nswhere j arrings or vibrations would eend t0 loosen ehe nues; and ie hasf0r its object ehe provision of very simple, inexpensive and effioientautomaeic means f0r locking the nues when serewed up eighe and withoueany pos sibility 0f their beeoming aecideneally loosened.

The noveley 0f my invention Will be hereinafeer more pareicularly seeforeh, and specifically pointed 0ut in ehe elaims In ehe aceompanyingdrawings, Figure 1 is a seetional end elevation 0f a railwayrail Withfish-plaees 0r other plaees applied theret0, wieh a c0nneceing-boltequipped Wlll1 h my improved nut-loek meehanism. Fig. 2 is a sideelevation 0f Fig. 1 lo oking tovvard the left. Fig. 3 is a deeaehedelevation 0f ehe nut-looking (10g.

The same leeeers 0f reference are used eo indicaee ideneical pares inall ehe figures.

In the drawings an ordinary railway-rail is shown of which A is ehehead, B ehe web, and C the foot.

D represenes the plaees, whether fish-plaees 0r other plzeees, fieeed eoehe web between the under side 0f the head and ehe upper side of thefooe 0f the rail zend E is ehe connectingbole passed through aperforation in the plaees D and ehe web 0f ehe rail in ehe usual manner.

F is the head of ehe b0le-bearing against 0ne of the plaees D, in ehisinstance with an interposed plaee G reseing uponthe f0ot 0f tl1e rail,and provided Wieh a lug oi shoulder a f0r one 0f ehe faces 0f the head0f ehe bole eo rese up0n t0 prevene ehe turning 0f the b0le. Theopposiee projeceing ehreaded end of ehe bolt has sorewed upon ie theusual clamping-nue H, and ineerposed between seid nue and ehe adjaceneplaee D is whae I denominate a non-roeaeable dog-carrier I; Whi0h inehis insence is a plate with a perforation for the passage 0f ehe boleand which has feet b resting upon the f0ot 0f the rail to prevent eheeurning of the platte. This Provision 01 feee, however, is simply forehe purpose 0f ligheening ehe weight of the plaee, for ie might be solidae ies boeeom, Wieh 0ne coneinued bearing upon the fooe of the rail eoprevent ehe eurning 0f ehe plaee.

Suitably journaled in ehe plaee I and preferably ae ies inner side is agravitaeing dog J which in ehis instance is provided with trunnions p,confined in lateral recesses upon ehe rear face of the plaee I. 'Ihisdog projeces through a vertical slot or opening c, whose boteom Wallarrests ehe downward move ment 0f ehe Clog, as seeri by ehe doteedlines, Fig. 1, and ehe lengeh 0f ehe slot is such thae the d0g can beturned up completely wiehin ehe plaee, as also shown by the doteed linesin Fig. l, where it can be held by a mateh 01 pin inserted in anelongaeion (Z of 0ne 0f ehe erunnion-reeesses. The lovver edge 0f ehedog next eo ehe nue is beveled 0'ff, as seen ae e, Fig. 2, and eheloeation 0f the dog is such ehat when 0ne 0i ehe sides 0f the nue standsvertical, as in F ig. 2, the projeceing flat side 0f ehe dog restssnugly against seid side 0f ehe nue andeffeceually locks ehe sameagainst backward eurning, es Will be readily seen and understood, thoughin serewing the nut up ehe angles of the sides Will eake under thebeveled portion e of the d0gs and life it out 0f ehe way eo permit ehenue eo be serewed eighely eo place, and ehen when ehe side of the nutadjacent eo ehe dog is brought eo a vereical position ehe d0g Will drop0ut by graviey and Will engage with ehe side of ehe nutto lo cl it inplace.

VVhenever it is desired eo unscrew ehe nue, it is only necessary t0 liftehe (log and hold it up within the plaee I, es indicated by ehe doeeedlines in Fig. l, whereupon the nue can be readily unscrewed.

By ehe foregoing simple meens I have prob vided a nue-lock Which isehoroughly efficiene and noe liable t0 be broken er to get out 0f orderand ab ehe same time it is very simple and cheap in its construceion.

Having thus fully described my invention, I claiml. In nut-lockconstruction, the combination of a skeletomdog carrier provided withlegs 130 prevent its rotation when slipped o0 place over the threadedend 0f the holt, a gravitating dog pivoted t0 one side of said carrierin the rear Wall thereof, a cavity in said carrrier terminating in as10t 130 perr nit the dog to be projected from the front Wall 0f thecarrier against the side Wall 0f the nut screwed upon the end 0f theb0lt and bearing against the earrier t0 100k the nut from turning, andan opening in the edge of said carrier adj acent t0 the dog t0 permitthe introduction 0f a pin for holding the dog up when raisiad within thecarrier, substantia]ly as described.

2. In nut-loek construotion, th6 COInbinei tion of adjoining ends 0f therails, fi shplates embracing the rails 011 bo th sides of the joint,bolts uniting said fish-plates and rails, a separate dogcarrier for eachbolt upon the threaded end 0f the holt and bearing againso the adj acentfish-plate and resting upon the foot of the rail, a nut screwed up0n theprojecting end 0f the bolt and bearing against the dogcarrier, and agravitating dog J pivoted in a vertical opening through said carrier,said d0g having its under ed e adjacent t0 the nut beveled ofl,substantial%y as described.
